Yea, I had a fairly in depth break down of this and lost the text somehow so I'm going to keep it simple.

1.19 Repair updates are spectacular. They are exactly what the repair system needs to become reasonable after having removed 90% of the system.

1.20 Updates are ridiculous, they are completely unnecessary and make literally no sense. It is once again removing what little depth the crafting classes have and is counter productive to Yoshida's own plan to give crafters influence over the economy.
